Title:
Low-Temperature Properties of Single-Crystal ${\mathrm{CrB}}_{2}$ 
Abstract:
We report the low-temperature properties of 11B-enriched single-crystal CrB2 as prepared from high-purity Cr and B powder by a solid-state reaction and optical float zoning. The electrical resistivity, $̊ho$xx, Hall effect, $̊ho$xy, and specific heat, C, are characteristic of an exchange-enhanced Fermi liquid ground state, which develops a slightly anisotropic spin gap $\Delta\approx$220K below TN=88K. This observation is corroborated by the absence of a Curie dependence in the magnetization for...    »
